T0 all whom z'kmay concern.:

Be it known that I, ERAs'rUs E. VVINELEY,

Lynn, in the county of EsseX'and State of Massachusetts, have invented certain new and useful Improvements in Heel Presses; andi do hereby declare the following to be a full, clear, and ,exacte description of the invention, vsuch asl willv enabley others skilled in the art to which 'it appertains to make and use the same.

This invention `rsively,and in which they `'are heldv under pressure for a substantial length of' time, and then discharged successively.

@ne object oi the invention is to produce a press, or' the type in question, vwhich may .be actuated withthe expenditure of ka small amount of power, such as maybe furnished,

for example,` by the actuation oi' a manuallyoperable lever or treadle. Machines ofthe `kind in question yhave heretoiorey f lbeen proposed in which a series/of 'clamping-devices, adapted` for holding, heel-piles the amounty of power necessary for operating the machine is reduced by the provision of means which act `lupon the clamping-dethe chain.

vices independently of their *movementswith f Other objects of' the invention are to im- Y prove the `construction and arrangement of t ie clamping-devices, and of the means tor vejecting the heel-blanks from the press, and

to these ends the invention resides in variy ous features cic construction whichk will be pointed out in connectionywith the ffollowing description of thepreferred embodiment of the invention. y K y ln the accompanying. drawings Figure l is a side-elevation of a mach-ine embodying thepresent invention. Fig. 2 is a vside-elevation of portions of the mechanismy shown inv Fig. 1, but on a larger scale. `Fig. 3 is relates kto a press; in 'to which articles vmay be introduced succesa detailed view," in side-elevation of `ar'ipart koit the actuating-mechanism. Fig.V 4 is a vertical section on theflin'e 4-4 in Fig. 2.

vF ig. 5 is a plan-view of appart oit themachine shown in Fig. 2; and Figs. 6 andv 7 are, respectiyely, anl endelevation and a side-elevation ofone of the clamps.'`r

The invention is illustratedfas embodied I in 'a machine which is designed particularly for receiving heel-piles immediately after they have been assembled, and for holding these piles under pressure for a suihcient length ottime to permit the drying of the held together.

The Vrmachine comprises two pairs of cement by which the layers of material are sprocket-wheels 10 and "12, about Which two a endless sprocketfchains 14 are stretched.

The wheels are` kjournaled on horizontal' shafts; 1 6 and 18 supported upona framework 20, the wheels of each pair being integraland turning rloosely on the correspondingshaft.

The chains 14v support a series of clamps. Aps-fshown particularly in Figs.,6 and 7, each clamp comprises a base-plate 22 which .is screwed upon specially formed links of the. two chains.v The heel-pile is clamped between two jaws inthe form :of plates 24 and 26, with fiat opposite faces. The jaw ,24 is mounted on the-outer endof a plunger 28 which kslides in guideway 30 projecting inwardly from the base-plate 22. el spring 32,*enclosed within the guideway and acting upon a' shoulder on theplunger, tends to move' the jaw 24 towards the aw 26, but this movement is limited, .when the clamp is empty, by stop-nuts 34 on the free endv of the plunger. t i

The jaw 26 yis provided with two trunnions 36` which are received in holes in two arms v and 40. rigidly to the base-plate 22 while `the arm 40 is mounted, on a pivot 42, betweenparal-` lel lugs 43 projecting from the guideway f 30. A lug '44, integral with. the arm. 40,

kprojects between the `lugs 43 and is connected to one end of a vtension-spring 46,

The arin 38 is iiXed` icc otwhich the otherend is connected to the gui'deway. This spring tendsy to swing the arin40 towards the arm. 38,'andA thus to maintain the engagement between the arms andthe trunnions 36.k The arms are provided each with av 'series of holes, however,

` ticularly in Figs. 2, 4 rand 6.

and in adjusting the machine for heel-piles oie diierent heights the arm 40 maybe swung away from the arm 38, thus releasing the trunnions, which may then be introduced into any pair of the holes so as to f `the sprocket-wheels 12, and each plate 4B carries a series loff pivot-studs 50, upon which bell-crank levers 52 are mounted. The shorter arm of each lever is connected to a hook 5i, by meansoi a pivot 56. rlhe hooks `cooperate with pins 60 which project in opposite directions from lugs 58 integral withy each or" the clamp-jaws 24.

The hell-crank levers 52 are actuated by means of two stationary cam-discs 62, of

which one Ais iixed on the shatt 1S, while the similar in ormand position, the correspond-` other is screwed. to the frame oi the vmachine. Each hell-crank lever carries a roller 63 which engages the periphery of one of the cani-discs, and as the discs are exactly ing bell-crank levers. on opposite sides oi' the machine are actuated simultaneously in consequence of the rotation of the sprocketwheels and the plates .48 about the shaft 1S.

Each hook 54 is provided, as shown in dotted lines inFig. 2, with a lug 65 which i is engaged by one end of a spring 64. The

spring is coiled around the corresponding pivot and engages, at its other end, a pin 68 projecting from the plate 48. This spring' tends to swing the hook upon the pivot in a.counter-clockwise direction, as seen in Fig. 2, but this swinging movement is limited the engagement of a secondi Ylug 70, upon the hook, with a stop-pin 72 projecting from the bell-crank lever. The spring 64 also acts to rock the bell-crank lever inV a direction to hold the roller 63 in engagement with the cam 62.

Assuming the sprocket-wheels to rotate in a counter-clockwise direction inl Fig. 2, each cam-roller 63, when at the bottomfof the corresponding cam, engages a high point y.upon the cam-surface.

The corresponding hook is thereby retracted toward the centre of rotation. At the same time the hook is swung rearwardly, upon the pivot 56, by the engagement of a stationary cani-member 76 with a pin 78 projecting laterally from the pin 60. The roller next encounters an inwardly-inclined' portion 710i? the cam-disc 62. whereu on the sarinfr-- rocks the/bellcarries a series oi" pins 92; i

encounter a rise 8O on the cam, which swings the bell-crank lever in a direction to cause the hook to pull the pin 6() inwardly, thus moving the clamp-jaw 24 away from the jaw 26 preparatory to the heel-pile from the clamp.

Ait the pointiwhere the chains, in their straight upper stretches, leave the 'sprocketwheels, it is necessary to disengage the hooks from thepins 60. Aliceordingly, the camej ectment of the discs v62 are provided with depressions 82,l

which permit the hooks to be moved outwardly (upwardly), and then, by the continued rotation et the sprocket-wheels, the pinsfS on each hook are brought into engagement with one or the other of two tripmembers 84 and located alongside the paths of movement oi the hooks. The tripmeinherSi is tixed on the upper end of lan upright 86 secured to one cam-disc 62, while the trip-member is fixed to a'plate A124i constituting a. part ofthe iframe of the machine. By engagement of the pins with 'the trip-members theI hooks are momentarily retarded, so that they are swung backwardly out ci engagement with Athe corresponding pins 60, and when the pins 7S have wiped past the .trip-members the pins 60 have passed beyond the paths of movement of the hooks.

titer the disengagement ot the hooks from the pins 60V the cam-rollers engage rises on the cani-discs 62, thus restoring the bell-crank levers to their original positions` and each hook is then carried idly vfrom the 'upper'to the lower part oit 4its path oit'movement.

The chains 14 are given a ystep-by-step advancing movement by means or treadlemechanism. *A ring 90' is i'ixed to one ofthe sprocket-wheels 10, and this ring mhe pins cooperate with a dog 94 connected, by a pivot 96, with a skeleton-'lever 98. This lever turns loosely on the shaft 16. The dog is held normallyin a downwardly-swung position by means of a spring connecting the dog andthe lever 9S, but the downward movement ofthe dog is limited by engagement of a stop-arm 102 thereon with a lug projecting from vthe lever 9ST as shown in.

` dotted lines in Fig. 3. hook. Accordingly.y the hook is held, at this time, within and behind the corresponding The lever y9S is connected, by a rod l102i,

The rock-shaft is journaled upon the 4frame of the machine, and a treadle-lever is fixed to the rock-shaft. When the treadle `with an arm 106 tired 'on a rock-shaft 108.

is depressed the lever 98 is swung in a direcf.

tion to ycause the dogi94-to push against one of the pins 92, and thus to rotatethe sprocketwheels 10. rlihis rotation is transmitted to the chains, and through them to the sprocketwheels 12 and the mechanism by which the clamps are opened. j

In order to limit thel movement or the chains so caused exactly to the amplitude of the space between two successive clamps, a detent-arm 116 is mounted on a pivot 118 projecting from the framework 20.,- This detent-arm is provided with a pin 122 which engages a cam-path 120 formed on the inner side of the lever 98. 'The vcam-path is so shaped that during the first `vpart or the movement, just described, or" the lever l98,

the /detent-arm is swung downwardly, so

that when the pin 92'which is at the moment engaged the dog 94 has beenfbrought to the required point it engages and is arrested by the end of the detent-arm, as shown in dotted lines invFig. 3.

The return-movement is imparted to the lever 98 and the treadle., by means/of av spring 112 which is attached, at one end, to the upper arm 114 or thelever 98 and, at the other end,-to the framework 20. This return-movementis limitedt by the engage` ment of the pin 122 with the closed end of the cam-path `120, as shown in. dotted lines in Fig. 1. l*

As each clamp, after receiving a heel-pile and passing through the entire path of motion provided by therchalin, returns to its original position., it is necessary to eject the heel-piley from theolamp to provide for lthe reception of a fresh pile. Since the paste by which the lifts of the heel-pile are securedtogether may also .stick the heel-pile to the clamp-j aw 24, means are provided for pressing the pile laterally with suiiicient force to loosen it from the jaw. For this purpose a-plate 126 (Fig. 5) is mounted upon the frame-plate 124, the plate 126 hav-- ing a beveled extremity which overhangs the clampfjaw 24, as the latter passes by. The beveled end of the plate 126 encounters the Vheel-pile and forces it laterally romits original position on the clamp-jaw 24. The jaw 24 is provided with a short tiange 128 on its rear edge, to prevent the pile trombe-l ing turned, by its engagement with the plate 126, sufficiently to interfere lwith the subsequent ejection of the pile from the clamp@ The heel-pileV is ejectedlaterally from the clamp by means of an ejector in the form oic a. plunger 130, which 'slides in a guideway 132 on the top of the plate 126, j The ejector is actuated'by means of an arm 134, which is pivoted on a stud 136- carried by one arm of a bell-crank lever 138. This `lever is mounted' on a pivot 189 risingfroni the ,frame-,member 124, and the longer arm oi the lever is connected, byfa link 140, with the plunger 130.' The armr 134 has va lug l'at its free end, and this lug liesnorinally in the path oi" movement of the pinsGO, Ac-

cordingljgas each pincomes in engagementl with the lug 135it, draws the arm 134 tothe lett,` thus rocking the bell-.crank lever 138 and causing the plunger 130 to strike the heel-pile in the clamp which at the time is in proper position, whereby the pile is ejected from the ,clampB `The arm 134` .is

provided with a-Kpin142 which projectsL downwardly into an inclined guideway 144 on top ofthe frame-member 124, and thisl guideway swings the arm .184 away from the pin .60, so as to cause the lug 135 to disengage the pin after suiiicient movement has f i been imparted to the ejector. yThe parts are then returned to their normal positiony bya tension-spring on the arm134.

146 which isattached to a lug The chain comes to yrest withf'the clamp j from which fthe heel-pile has just 2 been ejected, abreast of al gageeplate 152a This plate overhangs the depressed lower jaw of the.y empty clamp, and its edge serves as a against which the operator may press a `fresh heel-pile in introducing it to the clamp.-` `flhe gage-plate ismounted on the vtrame -member ,chine; Thejconnection of each clamp with a single link only of each chain does not interfere with the assumption or thek necessary `cur-:vature in ,thev chains in passing aroundthe sprocket-wheels, as shown in adj ustable,k

F ig. 2, but tosteady the clamps, when they are at thetop of the machine, each baseplate 22 is provided with depending proL jections 150 (Fig. 7) which engage links behind and in front of those -to which the baseplate is fixed.

The rpin-andhole connections" between the clamp-jawsv 26 and the arms 38 and 40,

beside providing for convenient adjustment as aforesaid, have also the advantage that they permit angular movement of the clamp-jaws by which they may accommodate themselves to the shapes offthefheelpiles; and while the vmachine is illustrated as operating on pileswith parallel upper and'lowery surfaces, it will beV apparent that "it will operate with equal facility upon piles in which wedge-lifts have been used and than at the breast. vl l v When used as a drying press forheel-piles the. present machine is preferably located close alongside 4the heel-building machine, and the operator of the latter, after the forwhich are, acccrdingly higher at the rear mation of each heel-pile, introduces it into 'a device to open the clamps successively actuated bv means other than the moving press structure, arenot claimed herein but will be 'found claimed in applicants (impending 7 application, Ser.
